Possible Bug in VMNG300 firmware?

[craigj2k12]

Right, firstly my little story (ill keep it short):
I had the superhub, was causing me problems, rang CEO office, got VMNG300

when i first typed that it was at least 30 lines!

Anyway the problem:
On the superhub I got channels 125, 126, 127 and 128, this is exactly the same on the modem. however upstream, on the superhub would mostly connect to channel 6, but if i restarted a couple of times it would get channel 5, which seemed a lot less utilised and gave me lower ping. On the modem it only gives me channel 6 (or so it would seem).... i posted on the VM forums and asked why I couldnt get 5 (i spent 45 minutes sat next to the modem pulling the power lead out and plugging it back in (yes im sad)) anyway the guy on VM forums told me that I was connected to channel 5, and double checking the modem stats it said channel 6, so does the modem have a firmware bug where it reports channel 5 as being channel 6?

if it is a bug, i can certainly see why is hasnt been picked up lol, i cant really see how anyone would notice it, unless in the same situation as me

Oh do you realise what you have started

well i wasnt going to post it after the farce the other day, but i thought it was well worth it, especially seeing as VM are paying me £12 an hour to take some attention away from the superhub

(thats a joke by the way)

It's not a bug, some hardware starts counting at 0, some at 1.

but its not put me on 7 (or 6 as it would be)

maybe thats why the superhub "wasnt that good", becuase it automatically puts you on saturated channels

I'm on channel 3 on my vmng300

Good or bad?

thats about all i can tell you, as im not on your port, or even your CMTS then I cant say whether channel 3 is good

[General Maximus]

I am on channel 3 as well. While we are talking about channels and ubrs i want to moan about that site everyone goes on about which shows the utilisation of the ubrs in your area. You have got 11 or 12 colours crammed together which is crap for colour blind people because I cant see which line is mine

See what you've started craig?

[General Maximus]

this was the one I was talking about http://ukinternetreport.co.uk/cmts/

Are these physically separate servers or are they cards sat within a server which customers are assigned to?

Either way, just as this site shows the latency of the ubrs serving a particular area, is their a report we can access which shows the latency or channel utilisation of each ubr we are on?

i.e if I know I am on linc11, is there anyway I can compare the upstream channels we are talking about?

Nope as even when I called up using the Superhub he said I was on channel 2 when I was on channel 3... So it makes no difference what modem/hub you have.

One of the things ignition told me was to check the frequency rather than the id as the id is cosmetic and can change even tho you on the same channel still. So if you can remember the frequency of the lower utilised channel and compare it to the one on the vmng300 you will know if it is different or not.

The last month or so I was on the superhub VM activated a 2nd upstream channel so I had channels 7 and 8, 7 was significantly lower utilised than 8 and yet the superhub 9 times out of 10 picked 8, my logic was that the superhub scans from top down (not other way) so unless there is a issue connecting to 8 then 7 wont get picked. Hence my trick of artifically reducing the signal to 8 by half removing the cable so 7 gets picked. A short time before I got the vmng300 the channel 7 changed to a docsis2 channel which looks like it merged in the channel 8 as well so the 2 smaller width channels merged into a single big width channel. As the last week or so on the superhub it seemed to keep picking channel 7. This has carried on to the vmng300 now I always get channel 7 and I did check the frequency which is the same as the channel 7 was on the superhub. So for me its either.

1 - still 2 channels but VM stopped the round robin and forced customers onto specific channels.
2 - is only 1 channel now its docsis2.
3 - as you say the vmng300 is acting odd, but its worth saying whenever I plugin my superhub it always gets channel 7 now as well. you should be able to do same test if your superhub is still activated.

[craigj2k12]

the superhub is still activates chrys, but im not sure it will work after the last beating i gave it, i was intending on introducing it to my airsoft gun, but i thought its better in one piece, especially if VM will want it back if i ever cancel.

ill plug it in sometime this week when iv got some time, and ill check the frequencies of the channels, im on the upgraded upload speed, so docsis2 16qam

About the only bug I can find is that it says "Channel Id" on downstream (I have 93-96), then the correct "Channel ID" on the upstream (5). Hardly a dealbreaker.

Although now I look closer, upstream power level is rated 57 dBmV, is that within nominal range? (Downstream is ~-0.3 for all four.)
